Here is a comprehensive breakdown on What Is Actually in Starbucks' Banana Cold Foam? Ingredients & Nutrition.

Cold foam feels airy on the palate, which often masks its caloric density. When layered onto an unsweetened cold brew, the banana cream topping completely rewrites the beverage's macro profile.

A single cold foam topping standard portion (roughly 100 ml before whipping) contains approximately 190 calories. The heavy dairy fat accounts for 8 to 10 grams of fat, including saturated fats from the cream. Carbohydrates land between 17 and 20 grams, almost entirely derived from the simple sugars in the banana syrup and vanilla sweet cream. While the 15 grams of whey protein offer genuine satiety, the beverage is far from a low-glycemic supplement.
